Manila Cathedral - The cathedral, also known as the minor basilica of the Immaculate Conception, was the seat of the Archbishop of Manila during the Spanish colonial period in the Philippines, and still remains the ecclesiastical seat of the Archdiocese of Manila. Completed in 1951, the Manilc Cathedral rises majestically over the remains of five predecessors, the first of which was erected in 1581. Four of the previous constructions were destroyed by earthquakes and fires, the fifth was reduced to a bombed-out shell during the Battle for Manila in 1945. The new Romanesque edificf incorporates stone carvings and rosette windows salvaged from the ruins.

St. Augustine Church (Paoay Church) - Popularly known as Paoay Church, St. Augustine Church was built in 1694 through the efforts of Augustinian friars led by Fr. Antonio Estavillo. Considered as the most outstanding variant of the "earthquake Baroque", the church was built of baked bricks, coral rocks, salbot (tree sap) and lumber, and has 24 curved buttresses. Earthquake damaged portions of the church in 1865 and 1885. In an excavation conducted inside the church in 2000, a prehistoric human skeleton and fragmented ceramics were discovered and are now on display at the National Museum. The Paoay Church was declared a national treasure by then President Ferdinand Marcos. Now included in UNESCO's World Heritage List, it revealed several structural decays after centuries of exposure to the elements and will soon undergo restoration under the auspices of UNESCO.

MANGALDAN owns the distinction as the third town in Pangasinan to be founded by the Dominican missionaries. As early as 1591, it already existed as a Spanish encomienda. Its foundation as a town is attributed to Blessed Juan Martinez de Santo Domingo who died a martyr's death in Japan on March 19, 1618.
